To all 7117710717. it 7724/,7 (ion/own.-

Be it known that I, lVILLmM COX, a subject of the I'Cing of GreatBritain and inland, and residing at 31 Dcrmcdy road. licwisham, Lcndcn,.lflngland, have invented a c i new and useful Driplrss Spout for T andthe Like, of which the following is a specificaticn.

This invention relates to improvements in those capillary devicesemployed with teapotspcuts, bottlfs, and the like,with the object ofpreventing a drop of water or other fluid from rolling down the outsideof the containing vessel.

The object of the present invention is to provide an improved device ofthis type applicabl to to acts and the like.

The inven vn consists in providing a capillary passage ceiniminicatingwith the inteitr' of i the X ssC-l and with the exterior oi the Eli atpoint bCloW the pouring edge, such that the drop remaining after pouringgravitatrs into the capii v passage.

The invention also comprisfs the improved forms of this device llfrcinafter (lTSC/iliXd, and illus ted in the accoinpanymg drawings, in

wh i e hlfigurcs 1 and 2 are side and front elevations, respectively,cta clawshap1d piece of metal for attachment to the spout or lip of aliquid-ccntainer, Fig. 1 being a section on the line A A oi Fig. 1. Fig.Sis a sectional side (i lieu of a spout, showing a metal claw-pitceattached ther to. Figs. t and. 5 are l'rcnt and side clevaticni-i,rcspmtivrly, of a wire beak l'cr attachmtnt to the spout. Fig. 6 is astcticn on the line B B of Fig. 5. Fig. 7 is a secticnal view of thespout, showing the beak, according to Figs. 1 and 5, attached the 8 and9 are sccticn and .l'rcnt view s, respectively, of a t ,i the invcntitnin which the capillary groove is formed in the spout itself.

An essential to this invention is hot from the print whe e thecapillary-passage meets namely, to .have gravlty assisting the capiltheexterior of the spent the capillary passage should sink below ahorizontal line drawn thrcugh its point of contact with the exterior ofthe spout. This is CSSCDtiJl, so that the drop gravitatcs into thecapillary passage, and its Wt ight thus assists instead of counteractsthe cepillinity.

According to one form I provide a suitable attachment to the vcss'il, asshown in Figs. 1 and 2, in which a claw-like or hooked piece of metal 6,having on its inner curve a capillary groove f or a slit,is slipped onthe spout, as shown in Fig. 3. The claw-like piece is placed over theedge of the spout or lip and pressed down, its pcint or hooked end 9 taking a position and gripping on the under side of the lip of the spout,and thereby catching the drop of liquid which travels to the end 9 andthen ilows by means of the capillary passage from the point 9 down thespout into the vessel when the vessel is brought to the upright positionor returned to its usual position. It will of course be understood thatif the capillary lilm or column of fluid be severed, say, at or near thetop of the lip or spout the drop will not be returned down the inside ofthe spout. It will be seen that the drop gray'itatcs into the capillarypassage.

Instead of forming tlc capillary device in the manner above described itmay be made of wire bent and arranged for capillary action to take placein tire manner liereinbcfore referred to. Tie wire may be bent to theform slown in Figs. 4 and 5 and passed down the spout, being ltcld inposition by the spring-pressure of the wire bearing against as spout.Tito wire is bent double to form a hook or beak h in side elevation, thelegs it being spread sli htly to a narrow V form in front elevation.'lie portions j and j of the wire forming the hook are close together,so t at capillarity may take place wlten tlre wire is wettcd during thepouring out of the liquid, tie capillary passage starting from a pointin tic exterior of tie spout below the pouring edge. The mode oi'-operation of this device is practically tlte same as that described wireference to Figs. 1 and 2; but I 'iind in practice that its operationis better tI'an tie claw-shaped device, and it is the best form atpresent known to me. In all cases, however, the beak should fall below ahorizontal line drawn from the point of contact with tie exterior ol thespout, so as to obtain tie el'l'cct aimed at in this inventionin Figs. 8and 9, where the spout is formed with a lip or enlarged edge m, in whichis provided a curved capillary groove Having now described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. A pouring-spout, a capillary passage as sociated therewith into whichthe drop left after pouring gravitates, said passage leading from apoint outside the pouring-spout below the pouring edge to the interiorof the spout.

2. A teapot-spout having a member provided with a capillary passageleading from a point below the pouring edge to the interior of the spoutsaid passage being arranged to fall below a horizontal line drawn fromits
